Yes, I thought the same. However we found a couple of cases where an actual weighing of the wheel was quite off from what the site told.
For example the Parabols. They are supposed to weigh 8,7kgs which is pretty nice. So nice in fact, that I wanted them to get as a next set of wheels, because I always loved the looks.
Together with that weight this would be a no-brainer.
But in reality they are somewhere in the 11kgs ballpark (dont remember the exact weight tho) and therefore more on the chubby side like S-lines. Meh.
I was so happy to find a comprehensive source of wheel information together with weight measurements.
What a bummer it was when I noticed that those pieces of information where sometimes correct and sometimes wild guesses.
